The human immune response to red blood cell antigens as revealed by repertoire cloning.
A major goal of current immunologic research is to develop specific therapeutic strategies by which the enormous diversity in immune response can be enhanced, attenuated, or eliminated, depending on the particular disease process. For nearly a century, the human immune response to red blood cell antigens has served as a paradigm for understanding the pathophysiology of autoimmune disorders and alloimmune reactions to foreign cells and tissues. Recent developments in molecular biology have facilitated the expression of immune repertoires in the form of immunoglobulin Fab fragments on the surface of filamentous bacteriophage. Such approaches have provided powerful means for producing monoclonal antibodies for research, clinical, and therapeutic applications. Our laboratory has combined these techniques with novel cell-surface selection methods to isolate extraordinarily large arrays of human antibodies to the clinically relevant red blood cell Rh(D) antigen. Our results have provided a comprehensive genetic and serologic analysis of anit-Rh(D) antibodies within single alloimmunized individuals thereby offering new insights into the development of human immune repertoires.
